CO₂ Valves: Technology and Manufacturing
How are CO₂ valves manufactured?
The manufacturing of our CO₂ valves involves a precise and optimized process that spans from material procurement to delivery. Every stage is designed to ensure the highest quality and safety.
The Development Process: From Concept to Production
Our development process begins with a detailed analysis of customer requirements. Engineers use CAD software to design valves that are both functional and efficient. Simulations and calculations help predict how the valves will perform under real operating conditions. After validation, the designs move from the prototyping phase to the pre-production phase. Once field trials are successfully completed, the products are transferred to mass production.
Prototyping and Simulation: Precision from the Start
Before a valve enters production, we create prototypes that are tested in-house in simulated environments and on-site at the customer’s facility. These tests ensure that the valves meet the requirements for pressure, temperature, and chemical resistance. Using state-of-the-art software solutions, we minimize errors and optimize designs at an early stage.
Material Selection: Why Stainless Steel and Optimized Sealing Materials?
For our CO₂ valves, we use only stainless steel and high-performance sealing materials for components that come into contact with the medium. These materials are specifically designed for use with CO₂ and are extremely wear-resistant. This ensures a long service life and minimizes maintenance requirements.
Assembly and Testing Procedures: Quality Steps in Detail
During the manufacturing process, our valves undergo rigorous testing procedures. These include:
- Leak teststo rule out leaks.
- Stress teststo ensure pressure resistance.
- Functional teststo ensure reliability in real-world applications.

Quality and Safety
What testing procedures ensure the performance of our CO₂ valves?
To ensure the quality and reliability of our CO₂ valves, we subject them to a variety of rigorous tests:
- Leak tests: Ensure that no CO₂ escapes and that the valves remain tight even under extreme pressures.
- Stress tests: Simulation of real operating conditions, including high pressures and temperatures.
- Long-term testing: Performance evaluation after millions of switching cycles to ensure durability.
These tests are carried out in our own laboratory and also in cooperation with our customers, who conduct tests under real conditions in their own equipment. This close cooperation ensures consistently high quality.
How do we ensure that CO₂ valves can withstand the highest pressures?
Our CO₂ valves are specially designed for high-pressure applications. To achieve this, we rely on:
- High-strength materials: Stainless steel and high-performance sealing materials ensure maximum pressure and corrosion resistance.
